Notes from the chart

  • Amounts are mL per US gallon, from Advanced Nutrients' USA Top Shelf and Master recipes.
  • Week 1 can be repeated for clones and seedlings. For a longer veg, repeat grow week 4. If your plants flower longer than 8 weeks, repeat bloom week 4.
  • Mix the water thoroughly after adding each product.
  • Advanced Nutrients says to cut base nutrient strength by 25 percent if you see tip burn. Bloom week 8 is a nutrient-free flush with Flawless Finish only.
  • pH Perfect bases are sold as self-buffering. Many growers here still check pH, especially with tap water.
  • All three parts run through the whole grow: the same three bottles at 4 to 16 mL in grow and 16 mL in bloom.

Common questions

Top Shelf or Master recipe?

Top Shelf is the base plus Advanced Nutrients' core add-ons. Master adds every product they recommend, including root expanders, Rhino Skin, Bud Factor X, Tasty Terpenes and Sensizym. The base amounts are the same in both.

Do I need all the Advanced Nutrients add-ons?

No. The base nutrients carry the nutrition. Untick the add-ons in the calculator to see the bases alone. Many members run just the bases plus one or two boosters.

Why does the calculator start at 75 percent?

Advanced Nutrients says to cut base strength by 25 percent if you see tip burn, and members commonly run around three-quarter strength. Raise it if your plants want more.

Still not sure? Ask the growers.

Post your nutrients, how much you're feeding, your medium and a photo. Members who've run AN Grow Micro Bloom will tell you what they'd change.
